I have a 2003 Mercedes Benz E320
And this appeared

 

Problem with the charging system or main battery. Your car is running off of the auxiliary battery and is shutting off non-critical systems. Your brakes take priority over blowers and what-not. Search and you will find many, many posts on this.


Just search on the term "W211 electrical consumers turned off".

 

The car can not run on auxiliary (SBC) battery.
That warning can indicate several different problems and in my case I had not torqued battery clamp bolts.
The car would start just fine and keep the voltage just fine, but occasionally message would appear and the darn thing killed AC blower.
Reading errors with SD would narrow the problem, but if you don't have easy access - starting with cleaning electrical connections has good chance to clear it.

 

I did un hook the negative trunk battery the day before ? Because my radio wasn't turning on Would that have an issue?

 

Once again, did you clean and torque the connectors?

 

No I just plugged them back in like nothing

 

Well... those cars are not forgiving nonchalant owners.

 

try to unplug the connections again, clean it and make sure you tighten it good.

 

Will do Tonight man I appreciate the help and suggestions

 

happened to my 211 before, main battery was goin south but didnt replace it till after almost a yr of that warning showing up every now and again so no need to worry.

 

Do I need to clean anything or buy anything at the moment ?

 

no need, just clean the ports real well, sand it a bit with fine sandpaper and wipe with dry cloth then make sure you re-tighten it well.

 

Will the warning go away at all ?

 

no! it will stay there forever!

jk, its worth a shot mate.

 

It will stay in the "stored" state of the car, until your Indy clears the faults...

 

Today my car is completely dead no battery running through

 

when was the last time you change your main battery?

 

It's been since about 6-7 months
Would you think it's the voltage regulator?

 

could be anything, voltage regulator, alternator or even a faulty battery. Get tripple a to jump start your car and bring it to an indy with a scanner that knows mb's.

 

The bad thing is that my trunk won't even open I tried it with my key and no luck..

 

did you try the metal key to open the boot/trunk?

 

Yeah I did and no luck

 

i can't believe how much this site as changed, everyone knows everything.
that warning means what it says, shutting off consumers due to low batt voltage.
either your batt is on the way out or something is draining it, start with that.
for the trunk, were you able to turn the mechanical key?, if yes that trunk should open by holding the key turned and squeezing the handle together

 

Really? It disappears from the display though. When I had it on mine it wouldn't linger after being solved, never needed to clear it.

 

as soon as the battery as proper charge to maintain consumers that display will go away.
